Contractor Dispute Over Scope of Work: How to Resolve It Without Court

You hired a contractor. They delivered something. It is not what you expected. They say it is. You say it is not. This is a contractor dispute over scope of work, and it is one of the most common commercial conflicts in Australia.

Most scope disputes can be resolved without going to a tribunal. The tool that does the work is a notice to remedy breach — a formal document that identifies the gap between what was promised and what was delivered, gives the contractor a chance to fix it, and protects your position if things escalate.

What is a scope of work dispute?

A scope of work dispute arises when the client and contractor disagree about what was included in the original agreement. Common examples:

• A web developer delivers a site without the agreed e-commerce functionality
• A tradie completes a renovation but leaves out fixtures specified in the quote
• A consultant delivers a report that does not cover the agreed research areas
• A graphic designer provides fewer design concepts than the contract stated
• A builder uses different materials than those specified in the scope

The contract (or quote, or statement of work) defines what should have been done. The dispute is about whether that standard was met.

Why scope disputes happen

The scope was never clearly defined. Verbal agreements, vague quotes, and emails that say “the usual” create room for different interpretations. If the contract does not specify deliverables, timelines, and quality standards, both parties are guessing.

Scope creep occurred without documentation. The client asked for extras during the job. The contractor assumed they were included. No one documented the change or the additional cost. Now both sides have different expectations.

The contractor misunderstood the brief. They thought “basic website” meant a landing page. You thought it meant five pages with a contact form. The gap was not intentional — it was a failure to confirm details upfront.

Quality standards were not defined. The contract said “professional standard” or “fit for purpose” but did not specify what that meant. One party’s professional is another party’s substandard.

What the law says about scope of work

Australian contract law does not require every detail to be written down, but it does require the parties to have a common intention about what was agreed. If there is no written contract, courts and tribunals typically look at:

• Quotes, invoices, and emails exchanged before the work started
• Industry standards for similar jobs
• What a reasonable person would have understood the scope to include
• Any conduct during the job that shows what both parties thought was agreed

Under the Australian Consumer Law, services must be:

• Rendered with due care and skill
• Fit for the purpose you told the contractor about
• Delivered within a reasonable time if no time was specified

If the contractor fails to meet these guarantees, you have the right to ask them to fix the problem at no extra cost. If they refuse or cannot fix it, you can claim a refund or compensation.

Review your contract or agreement first

Before you escalate, confirm what was actually agreed. Gather:

• The signed contract, quote, or statement of work
• All emails, messages, or texts discussing the scope
• Any variation requests you made during the job
• Photos, screenshots, or other evidence of what was delivered

Ask yourself: Did the contractor deliver what the contract said, or what you assumed? If the contract is vague or silent on a key deliverable, your legal position is weaker. If the contract is clear and the contractor missed it, you have a strong case.

Try to resolve it directly

Most contractors want repeat business and good reviews. Before you send a formal notice, try a direct conversation:

• Explain the gap between what was agreed and what was delivered
• Reference the specific clause or line item in the contract
• Ask how they plan to remedy the issue
• Propose a reasonable deadline

If the contractor agrees to fix it, confirm the plan in writing (email is fine). If they refuse, deny there is a problem, or go silent, move to the next step.

Send a notice to remedy breach

A notice to remedy breach is a formal letter that:

• Identifies the specific term of the contract that was breached
• Describes how the contractor failed to meet that term
• Gives the contractor a reasonable period (usually 7–14 days) to fix the problem
• States what will happen if they do not remedy the breach

This notice serves three purposes:

1. It clarifies your position. The contractor now knows exactly what you say is wrong and what you expect them to do.
2. It creates a paper trail. If you end up in a tribunal, you can show you gave the contractor a fair chance to fix the issue.
3. It often prompts action. Many contractors will remedy the breach once they see you are serious and organised.

The notice must be specific. Do not say “the work is not up to standard.” Say “Clause 3.2 of the contract required the website to include a booking system integrated with Stripe. The delivered site does not include this functionality.”

What to include in your notice

Your notice should cover:

• Your details and the contractor’s details — names, addresses, ABNs if applicable
• The contract date and reference number — so it is clear which agreement you are referring to
• The specific breach — the clause or term that was not met, described in plain language
• Evidence of the breach — photos, screenshots, expert reports, or other proof
• The remedy you require — what the contractor must do to fix the breach
• The deadline — a reasonable timeframe, typically 7–14 days from the date of the notice
• The consequence — what you will do if the breach is not remedied

Send the notice by email and registered post. Keep proof of delivery.

What happens after you send the notice

If the contractor remedies the breach: Problem solved. Confirm in writing that the issue is resolved and the contract is back on track.

If the contractor disputes the breach: They may respond saying they did meet the scope, or that the scope changed, or that you approved the variation. Review their response. If they have a point, negotiate. If they do not, you may need to escalate.

If the contractor ignores the notice: After the deadline passes, you have options:

• Withhold payment if you have not yet paid in full (but only withhold the amount related to the breach, not the entire invoice)
• Engage another contractor to complete or fix the work, then claim the cost from the original contractor
• Terminate the contract if the breach is serious enough to justify it
• File a tribunal application to recover your loss

When to take it to a tribunal

If the contractor will not fix the problem and the amount in dispute is under the tribunal limit in your state (typically $10,000–$25,000), you can file an application with your state’s civil and administrative tribunal:

• NSW: NSW Civil and Administrative Tribunal (NCAT)
• VIC: Victorian Civil and Administrative Tribunal (VCAT)
• QLD: Queensland Civil and Administrative Tribunal (QCAT)
• WA: State Administrative Tribunal (SAT)
• SA: South Australian Civil and Administrative Tribunal (SACAT)
• TAS: Tasmanian Civil and Administrative Tribunal (TasCAT)
• ACT: ACT Civil and Administrative Tribunal (ACAT)
• NT: Northern Territory Civil and Administrative Tribunal (NTCAT)

The tribunal process is designed for self-represented parties. You do not need a lawyer, but you do need evidence. Your notice to remedy breach becomes a key piece of that evidence — it shows you acted reasonably and gave the contractor a chance to fix the issue.

Frequently Asked Questions

Can I withhold payment if the contractor did not deliver the full scope?

You can withhold the portion of payment that relates to the undelivered or defective work, but you must pay for the work that was completed to standard. Send a notice to remedy breach first, explaining what is missing and giving the contractor a chance to fix it. If you withhold the entire payment without justification, the contractor may have a claim against you.

What if there is no written contract — just a verbal agreement?

Verbal contracts are legally binding in Australia, but they are harder to prove. Gather any emails, text messages, quotes, or invoices that show what was agreed. A tribunal will typically consider industry standards and what a reasonable person would have understood the scope to include. A notice to remedy breach is still useful — it forces both parties to state their version of the agreement in writing.

How long should I give the contractor to remedy the breach?

A reasonable timeframe depends on the nature of the breach. For minor fixes, 7 days is standard. For larger remedial work, 14 days is more appropriate. The key is that the deadline must be realistic — if you give an unreasonably short deadline, a tribunal may find you did not act in good faith.

What if the contractor says the extra work was out of scope and wants more money?

If you asked for work beyond the original scope, the contractor is entitled to charge for it — but only if they told you at the time that it was extra and would cost more. If they did the extra work without mentioning the cost, they cannot surprise you with a bill later. Review your contract and any emails to confirm what was agreed.

Can I use a notice to remedy breach if the contractor has already been paid?

Yes. A notice to remedy breach is not about withholding payment — it is about requiring the contractor to fix a problem. Even if you have paid in full, you can send the notice and demand that the contractor return to remedy the defective or incomplete work. If they refuse, you can claim the cost of engaging another contractor to fix it.
